Introduction Laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB) are acceptable options for primary bariatric procedures in patients with body mass index (BMI) 35–55 kg/m2. Aim The aim of this study is to compare the effects of these two bariatric procedures 6, 12 and 24 months after surgery. Material and methods Two hundred and two patients were included 72 LSG and 130 LAGB patients. The average age was 38.8 ±11.9 and 39.4 ±10.4 years in LSG and LAGB groups, with initial BMI of 44.1 kg/m2 and 45.2 kg/m2, p = NS. Results The mean percentage of excess weight loss (%EWL) at 6 months for LSG vs. LAGB was 36.3% vs. 30.1% (p = 0.01) and at 12 months was 43.8% vs. 34.6% (p = 0.005). The greatest difference in the mean %EWL at 12 months was observed in patients with initial BMI of 40–49.9 kg/m2 in favor of LSG (47.5% vs. 35.6%; p = 0.01). Two years after surgery there was no advantage of LSG and in the subgroup of patients with BMI 50–55 kg/m2 there was a trend in favor of LAGB (57.2% vs. 30%; p = 0.07). The multiple regression model of independent variables (age, gender, initial BMI and the presence of comorbidities) proved insignificant in prediction of the best outcome in means of %EWL for either operative modality. None of these factors in the logistic regression model could determine the type of surgery that should be used in particular patients. Conclusions During the first 2 years after surgery, the best results were obtained in women with lower BMI undergoing LSG surgery. The LSG provides greater %EWL after a shorter period of time though the difference decreases in time.

The aim of this study was to develop a less-invasive transanal endoscopic microsurgery (TEM) operative technique that could be applied in severely ill patients. Modified technique of TEM operation with use of the TriPort Access System in place of the operative rectoscope was designed. Harmonic scalpel and regular laparoscopic instruments were used. Resection of the rectal stump tumor was performed. A 71-year-old male patient with recurrent adenocarcinoma T2N0M0 in rectal stump and ASA 4 was operated using presented technique with good outcome. Total operating time was 25 minutes. There were no adverse events during or after the procedure. Patient was fully mobilized directly after the procedure. Proposed technique can be performed in severely ill patients as it avoids anal sphincter divulsion and therefore general anesthesia. Standard laparoscopic instruments can be used at no extra cost and no need for additional skills.

In recent years, multiple studies have proved laparoscopic total mesorectal excision (TME) to be as safe and as effective in rectal cancer treatment as open surgery, with the undeniable benefit of perioperative trauma reduction. Decreasing the number of incisions and performing single-port surgery could have further reduced the trauma. A new access device, QuadPort™ Olympus, enables operations from just one small transumbilical incision, leaving a barely visible scar afterwards. This is one of the first reports of transumbilical laparoendoscopic single-site TME for rectal carcinoma. A 73-year-old woman presented with tubulo-villous adenoma with high-grade dysplasia and focal adenocarcinoma in situ at 7 cm from the anal verge. She had TME performed via a QuadPort™, Olympus, in line with principles of laparoscopic TME. The operating time was 80 min. There were no adverse events during the procedure. Total blood loss was less than 100 ml. There were no complications in the postoperative period. The patient required only non-opioid analgesia, during the first 2 days. The patient was discharged on the 3rd postoperative day with standard recommendations. Feasibility and safety of the proposed transumbilical laparoendoscopic single site TME for rectal carcinoma was proved. It is a technically demanding procedure, requiring appropriate laparoscopic skills. The QuadPort provided good oncological protection of the wound and easy specimen extraction. Reduced operative trauma resulted in no opioid administration in the perioperative period. Hospital stay was comparable with laparoscopic TME but the cosmetic effect was much better.

Introduction Among the most common early complications after bariatric surgery are anastomosis leak and bleeding. In order to react quickly and perform accurate treatment before the clinical signs appear, early predictors should be found. In the study C-reactive protein (CRP) and procalcitonin (PCT) levels were investigated. Characterized by a relatively short half-life, they can predict surgical complications. Aim To develop and implement certain standards for early detection of complications. Material and methods The study involved 319 adults who underwent laparoscopic sleeve gastrectomy (LSG) as a surgical intervention for morbid obesity at the Department of General Surgery of Ceynowa Hospital in Wejherowo. Every patient had CRP and PCT levels measured before the surgery and on the 1st and 2nd postoperative day (POD). Results Early postoperative complications occurred in 19 (5.96%) patients. Septic and non-septic complications occurred in 3 and 16 patients respectively. Among the patients with septic postoperative complications CRP level increased significantly on the 2nd POD compared to the remainder (p = 0.0221). Among the patients with non-septic postoperative complications CRP level increased significantly on the 1st and 2nd POD compared to the remainder. Among the patients with septic and non-septic postoperative complications PCT level increased significantly on the 2nd POD compared to the remainder. Conclusions The CRP and PCT level are supposed to be relevant diagnostic markers to predict non-septic and septic complications after LSG.
